WILLIAM RICHARD COLMAN, OF QUINCY, ILLINOIS.

BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 767,631, dated August16 1904,

Application filed January 22, 1908. Serial No. 140,184. (No model.)

To all whom it may concern:

Be it known that I, WVILLIAM RICHARD CoL- MAN, a citizen of the UnitedStates, residing at Quincy, in the county of Adams and State ofIllinois, have invented a new and useful Baling-Press, of which thefollowing is a specification.

This invention relates to a baling-press, and more particularly to thefeeder and its operating mechanism.

One of the objects of the invention is to equip a power-operated presswith an oscillatory feeder arranged to be intermittently operatedthrough the medium of a trip-arm disposed in the path of thepitman-head, the arrangement being such that the feeder will beprojected through the feed-throat of the press and retracted to itsnormal position in the briefest possible space of time in order that itmay have a maximum period of rest, during which the hay or othermaterial to be baled may be fed to the press-box or to the feedhopperabove the same.

Another object of the invention is to so mount the head of the feederthat it will retain its plumb or vertical positionduring its movementinto the press-box to pack the hay, this object being attained by soconnecting the feeder-head with the swinging arms of the feeder that theangular disposition of the head with respect to the arms will be variedduring the downward movement of the latter.

A still further object of the invention is to so organize the feedingmechanism as a whole that it may be readily applied to presses alreadyin use and to so connect the trip-arm with the various otherfeeder-operating elements that the press may be operated in a reverse orbackward direction without endangering the integrity of the mechanism.

To the accomplishment of the several objects stated and otherssubordinate thereto the invention in its preferred embodiment resides inthat construction and arrangement of parts to be hereinafter described,illustrated in the accompanying drawings, and succinctly defined in theappended claims.

In said drawings, Figure 1 is a side elevation of a portion of abaling-press equipped with my improved feeding mechanism, the

depressed position of the feeder and the corresponding positions of theother parts being indicated in dotted lines. Fig. 2 is a rear endelevation of the subject-matter of Fig. 1, the upper portion of thefeeder being broken away. Fig. 8 is a detail sectional view illustratingthe mounting of the trip-arm and the manner in which the latter isindependently moved to prevent the possibility of deranging the partswhen the press is operated in a reverse or backward direction. Fig. 4 isa detail view in elevation of a portion of the subject-matter of Fig. 3:and Fig. 5 is detail view of a portion of the feeder, one position ofthe parts being shown in dotted lines and the figure being designed toillustrate the manner in which the angular relation of the feederheadwith respect to the arms is automatically changed to keep the head in asubstantially vertical position during the portion of its movement whichis effective to pack the hay.

Like numerals of reference are employed to designate corresponding partsthroughout the several views.

1 indicates the frame of a press, a large portion of which (includingmost of the pressboX 2) is broken away. At the rear end of this frame 1is located the power or press-opcrating mechanism, belted or otherwiseconnected to an engine or the like and arranged to operate thepress-plunger 3, which reciprocates in a manner well understood in theart to compress successive charges of hay or other material fed into thepress-box from above.

The power mechanism includes a powershaft 4, journaled in suitablebearings and to which are keyed a fly-wheel 5, a band-wheel 6, and apinion 7. The pinion is in turn geared to a comparatively largegear-wheel 8, keyed or otherwise secured upon a shaft 9, which is alsoprovided with a pair of pinions 10 and 11, meshing with a pair ofdrivinggears 12 and 13, mounted on stud-shafts 14, projecting inwardlyfrom opposite sides of the frame. The driving-gears are designed torotate in unison and are connected by an eccentrically-disposedwrist-pin 15, which passes through the bifurcated rear end or head of apitman 16, the opposite extremity I of which is pivotally connected tothe plunger It will therefore appear that as thedriving-gears arerotated the head or plunger 3 will be given a reciprocatory movement.

The bifurcated end of the pitman 16 straddles an antifriction-roller 17,mounted on the wrist-pin and arranged to strike and swing atrip-arm orfeeder-operating arm 18, extending radially from a shaft 19. disposedhorizontally beyond the rear end of the frame 1 and preferably journalcdin bearings 20, as shown. The arm 18 is mounted to swing independentlyon the shaft 19 when urged in one direction, (indicated by the arrow inFig. 3,) but when moved in the opposite direction ashoulder 21,withwhich said arm is provided, is arranged to, contact with a shoulder22, constiti'iting one end of a slot 23 and in one side of a sleeve 24,which encircles the shaft 19 and is rigidly secured thereto, as byset-screws 25. It will therefore appear (assuming the arm to be in itsnormal position, as indicated at Fig. 3) that the movement of the arm inone direction will be entirely independent of the shaft, While itsmovement in the opposite direction will effect the rotation of theshaft, and thereby operate any mechanism which may be connected to theshaft formovement therewith. The mechanism which is connected with theshaft 19 for operation thereby is the feeder; but before proceeding todescribe the latter it may be stated that the sleeve 24 and the arm 18are provided with lugs .26 and 27, connected to the opposite ends of aspring 28, which serves to return the arm 18 to its normal positionafter the latter has been swung to the position shown in dotted lines inFig. 3 and the wrist has passed beyond its end. At its opposite ends theshaft 19 is provided with crank-arms 29, connected by long linkswitlrcrank-arms 31 at the opposite ends of the feeder-shaft 32, mountedin suitable bearings 33, supported by the press-frame and carrying anoscillating feeder 34. Obviously this duplicate connection between theshaft 19 and the feeder need not be employed, as a single series ofconnecting elements is all that is necessary to effect the desiredcooperative relation of the parts.

The feeder 34 comprises a pair of arms 35,eX- tending radially from theshaft 32 and normally disposed in a substantially upright position, asindicated in Fig. 1. These arms are connected at theirlower ends by atransverse plate 36, bolted or otherwise secured in place, and extendbelow or beyond the shaft 32, where their extremities contact withretainingsprings 37, mounted on the frame and designed topresent'sufficient frictional resistance to the arms to preventpremature downward swinging of the feeder.

tionto the arms 35 the feeder comprises a feeder-head 38, consisting ofa pair of side bars 39, connected at their outer ends by a shoe 40 andprovided at their ends opposite in addi-- the shoe with slots 41 for theaccommodation of pins 42, projecting outwardly from the side bars of thefeeder. The feeder-head is thus capable of limited endwise movement in adirection transverse to the arms 35 and is urged in one direction bysprings 43, bolted upon the arms 35 and bearing against the adjacentextremities of the side bars 39 of the feederhead. In addition to theslot-and-pin connection between the feeder-head and the arms links 44are connected at their opposite ends to the arms 35 and side bars 39 atpoints somewhat removed from the pins 42, these links being provided forthe purpose of compelling the feeder-head to change its angular relationwith respect to the arms 35 whenever it is moved in an endwisedirection, the reason for which will presently appear.

The operation of the device is as follows: Assuming the parts to be inthe positions shown in full lines in Fig. 1 and the driving- Wheels tobe rotating in the direction indicated by the arrow in said figure, thewrist or the roller 17 thereon will strike the feeder-operating arm 18and will swing it to the position indicated in dotted lines. Theshoulders 21 and 22 of the arm 18 and sleeve 24 being in engagement, theshaft 19 will be rotated to swing the crank-arms 29, correspondingmovement being imparted tow the crank-arms 31 through the intermediatelinks. The swinging of the arms 31 will effect the partial rotation ofthe feeder-shaft 32, swinging the feeder toward the press-box andbringing the shoe of the head 38 in contact with the hayin the hopper.In order that the head 38 may be disposed in a substantiallyverticalposition as it moves down into thebody of hay, it is dis posed normallyat a more or less acute angle with respect to the arms 35 of the feeder,as shown in full lines in Fig. 5. Obviously, however, this would resultin a progressively greater inclination of the feeder-head during itsmovement into the press-box as the feederarms approach the horizontal.It is for this reason that l have employed the slot-and-pin connectionand the links 44 between the feederhead and the arms 35. As theshoe ofthe head comes in contact with the hay and continues to move down theresistance opposed by the hay being greater than that of the springs 43will arrest the head, and the arms 35 continuing to move down, the pins42 traveling in the slots 41, the links 44 Will increase the angledefined by the arms and head, and this change. of the angular relationof these parts occurring during the effective portion of the movementofthe feeder will cause the head to maintain a substantially upright orplumb position while performing its work. As soon as the wrist haspassed beyond the end of the arm 18 the feeder will be retracted to itsnormal position by retracting-springs 45, each of which is secured atits opposite ends to an arm 29 and to one side of the pressframe, asshown in Fig. 1. As this complete operation and retraction of the feederis effected in little more than one-sixth of the time required for thecomplete rotation of the driving-wheels, which is of course the time ofone complete reciprocation of the plunger, the period of rest of thefeeder will be comparatively great, thus serving to permit a maximumquantity of hay to be fed to the press in the intervals between thedescents of the feeder. If, however, it should be necessary to run thepress backward or if this should happen by accident, it would beimpossible to derange the feeding mechanism thereby, because the arm 18if struck by the wrist moving in the reverse direction-that is to say,in the direction of the arrow in Fig. 8would simply move to thedotted-line position in said figure without affecting the feeder or theintermediate connections and. as soon as released would be drawn back toits normal position by the spring 28.

It is thought that from the foregoing the construction and operation ofmy baling-press will be clearly comprehended; but while the illustratedembodiment of the invention is believed at this time to be preferable Ido not wish to be understood as limiting myself to the structuraldetails defined, as, on the contrary,I reserve the right to effect suchchanges, modifications, and variations of the illustrated structure asmay be fairly embraced within the scope of the protection prayed.
